I was fortunate enough to get the chance to play with the Miyoo Mini handheld console early on. I have a V1 unit that came in a box instead of the popular carrying case that now comes with the V2 units.

Inside the box is the device itself with the generic SD card in it, a standard USB-C charging cable, a card reader, and a manual.

Miyoo Mini: Where to buy?

We recommend purchasing a Miyoo Mini from trusted and vetted resellers. Miyoo has an official store on AliExpress where the Miyoo Mini is sold for ~$60.

On Amazon, it’s slightly pricier but that’s the cost you pay for the Amazon convenience + fast shipment.

Recommended Tools

While the stock SD card has so far worked for me, many Miyoo Mini owners recommend replacing the unbranded memory card with a branded one.

For those looking to keep a large library of PS1 games, upgrading to a 64GB SD card seems perfect. Similarly, the stock card reader is bound to fail, so it’s best to invest in a branded card reader too.

Miyoo Mini: Basic Operation

Boot, sleep, wake:

Pressing and holding the power button for at least one second will boot the device. Pressing it once will put it to sleep, another tap on the power button will wake the screen.

The stock firmware offers several options once the device is powered on. In the Menu, you’ll find Recent, Favorite, Game, RetroAcrh, App, and Setting.

Recent shows you the most recent games you opened while Favorite will give you a list of your liked titles.

How to add a game to your favorite list on Miyoo Mini?

To add a game to your favorite list, simply highlight the game and press the Menu button. Here, you will have the option to open the game, add it to your favorite list, or remove it from your library.

Under “game”, you’ll see a host of stock emulators for various platforms.

Mine came with an emulator for some of the most popular consoles like Famicom, Game Boy, Game Boy Advance, SEGA, and PlayStation.

You’ll be surprised at the large library the stock SD card comes with, but you can always delete what you don’t need.

Other Menu options like RetroArch, App, and Setting are pretty straightforward.

Miyoo Mini: How to update firmware?

One of the first few things you’d want to do with your Miyoo Mini is to update its firmware.

Here are the steps you need to follow to update the firmware on your Miyoo Mini:

  1. Download the latest firmware from Miyoo’s website, unzip the file.
  2. Get your SD card, load it into the reader, and plug it into your computer.
  3. Go to the unzipped folder, select “The firmware,” copy the “.img” file, and paste it to the SD card root.
  4. Go to the “TF card” folder; copy the “Emu,” “miyoo,” and “RetroArch” files; and paste it to the SD card root.
  5. Eject the SD card reader from your computer, take the memory card, and insert it to the Miyoo Mini.
  6. Get your charging cable, attach it to a low-wattage wall adapter, and plug the Miyoo Mini.

At this point, the Miyoo Mini will automatically boot and install the updates.

It’s important that you do not touch the device whilst in the process of updating the firmware as you may risk bricking the Miyoo Mini.

  1. Wait for the Miyoo Mini to restart and show the battery charging screen.
  2. Unplug the device and remove the SD card.
  3. Take the card, load it into the reader, and plug it into your computer.
  4. Search for the “.img” file and delete it.

We recommend you try out the standard operating system first. If you play for nostalgia’s sake, then the stock OS should be fine.

However, if you like to maximize what this open-source console has to offer, then install Onion or MiniUI. Here’s how you do it.
